Chemical Cleaning Services

The challenge as we see it

When faced with a highly technical and potentially hazardous fouling problem, there is simply no substitute for specialized expertise, proven experience and advanced chemical-based solutions. Chemical cleaning involves the use of chemicals to remove various types of scaling, sludges and deposits by using the chemical properties of reactants and solvents for the purpose of dissolution.

Our differentiated value

At Veolia, we are problem-solvers dedicated to providing technically advanced chemical cleaning services in a safe, efficient and professional manner. We have more than 40 years of experience in the reactive and non-reactive chemical cleaning of industrial process equipment, such as boilers, condensers, heat exchangers, pipelines, cooling water systems, lube oil systems, reactors and towers. We have successfully completed numerous unit cleaning projects, including alkylation units, crude units and quench oil system degassing and decontamination.

Our chemical formulations are based on years of research and testing. Our chemical cleaning services give your company access to:

  • An experienced staff of expert chemists and engineers who will design a cleaning process to fit your individual plant's needs
  • A “toolbox” that combines a wide variety of chemicals, such as mineral acids, organic acids, oxidizing agents, alkaline materials and proprietary blends, to develop the optimum solution for your cleaning challenge
  • Chemical systems coupled with the most effective cleaning methods, such as fill-and-soak, high- and low-velocity circulation, foam, vapor phase, gelled fluids and spray techniques
  • Equipment custom-manufactured to provide effective cleaning for a broad spectrum of environments and applications
